Pure Data

Welcome to the Pure Data site!

This site is a contribution of the IEM to the Pure Data community. Every Pure Data user who wants to contribute is welcome to join this portal and write/contribute some documentation, reports, news, comments and announcing events. The site is run on a Linux server with Zope / plone and administrated and driven by the Pure Data community.

About Pure Data (aka "Pd" / "Pd Vanilla")

Pure Data (or just "Pd") is an open source visual programming language for multimedia. Pure Data is developed by Miller Puckette since 1996 and you can find it on his official website along with the official documentation and other related resources. This is the official "Pd" or "main distribution" and it is also known as "Pd Vanilla", but there are other forks or "flavours".

What's New? Pd keeps evolving! See the Release notes for details.
One of the most prominent new features in last decade has been the inclusion of the Deken library manager for easy access to community-developed external libraries that expand the capabilities of Pd such as Cyclone, zexy, and the computer graphics library Gem.

Main Pd flavours

Pure Data is an Open Source project and embraces derivatives. Notable flavours of Pd include:

Miller S. Puckette's original distribution of Pd.
Purr Data
This Pd Programming Environment started based on Pd-L2Ork 1.x but ported to an HTML5 GUI. The distribution includes pre-installed externals (most inherited from (the now unmaintained and deprecated) Pd-Extended which was used as the basis for Pd-L2Ork (and, consequently, this flavour). GUI externals made for Pd-Vanilla are not compatible to the HTML5 GUI front-end, and some GUI externals from Pd-extended haven't been ported yet. Note that there are also some incompatibilities/differences also in the core of Pd-Vanilla and Purr Data.
In the fall of 2021, Pd-L2Ork provided new releases including the HTML5 GUI port from Purr Data (with the caveats as remarked above). Note that there are also some incompatibilities/differences also in the core of Pd-Vanilla and Pd-L2ork.
Fully compatible with Pd Vanilla, but enhanced with some UI tweaks (also including tweaks from Pd-extended). It carries some pre-installed externals (but none from Pd-extended); most notably it has the ceammc library (that you can also install on Pd Vanilla).

For a more complete list, check the Distributions section on our Downloads page.

Pure Data is an open source visual programming environment that runs on anything from personal computers to embedded devices (ie Raspberry Pi) and smartphones (via libpd, DroidParty (Android), and PdParty (iOS). It is a major branch of the family of patcher programming languages known as Max (Max/FTS, ISPW Max, Max/MSP, etc), originally developed by Miller Puckette at IRCAM.

Pd enables musicians, visual artists, performers, researchers, and developers to create software graphically without writing lines of code. Pd can be used to process and generate sound, video, 2D/3D graphics, and interface sensors, input devices, and MIDI. Pd can easily work over local and remote networks to integrate wearable technology, motor systems, lighting rigs, and other equipment. It is suitable for learning basic multimedia processing and visual programming methods as well as for realizing complex systems for large-scale projects.

Algorithmic functions are represented in Pd by visual boxes called objects placed within a patching window called a canvas. Data flow between objects are achieved through visual connections called patch cords. Each object performs a specific task, which can vary in complexity from very low-level mathematical operations to complicated audio or video functions such as reverberation, FFT transformations, or video decoding. Objects include core Pd vanilla objects, external objects or externals (Pd objects compiled from C or C++), and abstractions (Pd patches loaded as objects).
